RyngThe universal device for production monitoring

An extremely simple system to measure productivity and efficiency of the feeding line.

In order to have an instant and precise measurement of the quantity of material transferred from the container to the hopper, allowing operators to take prompt action on the machine’s operating parameters and, above all, to be able to have information on the machine’s effective productivity, Piovan has designed and manufactured a special production monitoring system, called “Ryng”. Ryng is structured as a component that is inserted between the loading container and the storage hopper with a high-precision weighing device placed inside it.

The system uses proprietary software, set according to specific algorithms which “filter” and “interpret” the data it gathers and consequently indicate the actual quantity of transferred material. Ryng actually measures the quantity of material that the container loads into the hopper, providing information directly from the field and therefore allowing real-time comparisons to be made at any time between the machine’s expected production and its actual production. In addition, the software is programmed to exclude or reduce to a minimum any measurement fluctuations that may be caused by the inevitable vibrations felt throughout the feeder system due to the machine’s normal operation. So, the system achieves high precision measurements (with a maximum error rate of less than 1%).


● Monitors resin consumption in real time by gain-in-weight and totalizes resin consumption
●Tracks consumption tied to a production lot number
● Central control panel controls up to 80 individual Ryngs
● Simple in-line installation
● Optional local remote key pad monitor per individual receiver
